(1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3) belongs to quinuclidine derivatives. Quinuclidine derivatives are also widely utilized as homogeneous or heterogeneous catalysts in various asymmetric processes such as Morita–Baylis–Hillman reactions, Sharpless dihydroxylation reactions, and phase-transfer catalytic reactions. Quinuclidine is an organic compound and a bicyclic amine and used as a catalyst and a chemical building block. It is a strong base with pKa of the conjugate acid of 19.5. It can be prepared by reduction of quinuclidone.Safety of (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide

Stereocontrolled [11C]alkylation of N-terminal glycine Schiff bases to obtain dipeptides was written by Filp, Ulrike;Pekosak, Aleksandra;Poot, Alex J.;Windhorst, Albert D.. And the article was included in European Journal of Organic Chemistry in 2017.Safety of (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide This article mentions the following:

The use of various quaternary ammonium salts as chiral phase-transfer catalysts allowed effective and stereoselective radiochem. [11C]alkylation to obtain functionalized dipeptides. We herein report a broadly applicable procedure for the asym. [11C]alkylation of dipeptides to give labeled N-terminal peptides by using different [11C]alkyl halides. Contended stereoselectivities of the reactions were observed by using 11C-labeled alkyl halides, [11C]methyl iodide and [11C]benzyl iodide, and diastereomeric ratios with different specialized catalysts of 95:5 and 90:10 were achieved, resp. Accordingly, the straightforward synthesis of enantioenriched compounds should play a vital role in peptide-based radiopharmaceutical development and positron emission tomog. imaging. In the experiment, the researchers used many compounds, for example, (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3Safety of (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide).
